RATION OF ILLINOIS 'WRITING MACHINE COMPANY, OF CHICAGO, ILLINOIS, ACORPO- TYPE-WRITER.

SPECIFICATION forming part of Letters Patent No. 725,493, dated April14, 1903.

Application filed September 14, 1901. semi No. 75,390. (No model.)

One feature of the invention is foundinthe" provision upon thepaper-carriage of a storage-receptacle for the paper, such receptaclebeing open along its top line for the insertion of the sheet and havinga longitudinal groove, depression, or enlargement along its bottomadapted to receive the lower edge of the paper and to prevent anytendency of such edge to turn or curl up under the pushing power appliedto the sheet in forcing it into the receptacle.

Other features of the invention relate specially to the construction ofthe carriage-escapement devices, the tension devices regulating themotor-spring for sliding the carriage, and the arrangement of thestop-pins for limiting the reciprocating movements of the type-cylinder.

In the accompanying drawings, Figure lis a plan view, and Fig. 2 avertical section, of a type-writer embodying my presentimprovement.Figs. 3 and 4 are end views of thecarriage in different positions. Figs.5 and 6 are vertical cross-sections of the carriage in differentpositionsiof the latter. Fig. 7 is a partial elevation of the carriage,partly in section. Fig. 8 is a plan, and Fig. 9 a section on the line 99 of Fig. 8, of the carriage and motor devices. Fig. 10 is an elevationof the escapement, and Fig. 11 is asectional view at right angles toFig. 10. Figs. 12 and 13 are parts in different positions. Fig. 14 is aside wings at the top, and front and rear combs or slottedplatesA A toserve as guides for the key-levers.

vers for the three rowsare pivoted to shafts b b b respectively.

O'is the rotary sliding type-cylinder, furnished with an annular groove0 near its mid- Me to receive the arm e of the lever E, by which thesliding movementis communicated, and with a longitudinal inner groove 0to give room to the feather 0 upon the shaft 0, whereon the sleeve ismounted and supported. This shaft is suspended upon the pointed ends oftwo pivots c and 0 arranged in line with the shaft, and of these the onemarked a is secured in a bearing, split for a portion of its length andprovided'with a tightening-screw 0 The hearing 0 of pivot 0? may have adetent c to engage with said pivot, and the latter may have a milledhead, as shown. In my former machines the feather was formed upon theinside of the sleeve, and consequently was near the axis of the shaft,so that any "looseness between it and "the groove in the shaft wasmultiplied at the surface of the sleeve, causing imperfection in thealinement of the printed characters. .By the change which Ihave-made inthe location of the feather and groove they are now nearer the surfaceand farther from the axis, so that the looseness'referred to affects the'alinement much less than with the other construction. I V

In addition tothe parts above mentioned I have shown other parts of theprinting mechanism; but as the present invention is independent of theparticular mechanism I do not describe them nor illustrate them fully.They are, however, almost identical with the corresponding parts of myPatent No. 474,350, of May 3, 1892. v The paper-carriage of-my improvedtypewriter is provided with a paper-storage receptacle H, arrangedlongitudinally of the carriage and below the plane of theprintingcenter. The receptacle is open at the top, and the paper-feedrolls J and K are placed just above the opening, so they may serve asguides in inserting the paper and so they may also be used in pushingthe paper down into the receptacle. This receptacle differs from formerconstructions in that it is pro vided with a bottom longitudinal groove71., the mouth of which is somewhat contracted. This groove is solocated as to insure the entrance within it of the lower edge when thepaper is first inserted within the receptacle, and by contracting themouth of the groove said lower edge is prevented from any tendency whichmay be communicated to it by the forcing of the sheet into thereceptacle to turn upward toward the feed-rolls.

Of the feed-rolls that marked K is journaled in stationary bearings inthe end plates of the carriage and is provided with a milled head K,whereby it may be turned at pleasure. This roller also receives theline-spacing actuations through the gear K and pinion K from thefinger-lever K, having a pawl K meshing with said gear.

The movable roller J is journaled in horizontal slots J, open at oneside, in the end plates J of the carriage and is confined therein by theupper ends of levers J pivoted at J and provided with springs J confinedin barrels J, attached to the end plates and pressing against the lowerends of the levers. The power of springs J is regulated by setscrews JThe feed-rolls J and K may be forced apart and held out of contactduring the insertion of the paper by levers L, rigid upon the shaft Land operated by the finger-lever L The points of levers L press againstthe journal of roller J and are so shaped that when they have forced theroller away from its acting position they will retain it in the changedposition notwithstanding its tendency to return under power of springs Ialso provide the paper-carriage with an erasure-plate M, which swingsinto position so it will sustain the paper along the line which is beingprinted whenever the carriage is tipped back, thus avoiding allnecessity for moving the paper to bring it over the plate preparatory tomaking erasures. This movability of the plate is necessary, of course,to avoid interference with the printing operation, and I make itautomatic by supporting the plate upon pivots m at its ends andconnecting it by a crank m and rod M, pivoted at m to a stationary partof the machine, so that when the carriage is tipped back from theprinting-point upon its pivots M sustained in the end pieces M of thebottom frame, the plate will be rocked from a horizontal position (shownat Figs. 3 and 5) to a vertical one. (Shown at Figs. i and 6.) In thelatter position it is directly behind the line being printed, so thatcorrection can be made without moving the paper at all. The returning ofthe carriage to its normal or printing position rocks the erasureplateto its elevated position, in which it is entirely out of the way of thehammer or other printing devices.

The printing'hammer N may be secured to a lever N, mounted upon arock-shaft N located under the paper-storage receptacle, as shown. Thisrequires considerable length in the lever and permits a stroke longenough to render the hammer effectual in manifolding. The lever iscurved so it may not interfere with the receptacle, and it is actuatedby the slotted cam N the lever N pivoted at n and engaging said cam andreceiving its impulses from the connecting-bar N and lever N upon shaftD 1 The feeding movements of the paper-carriage are due to thehorizontal spring-actuated pulley Q and the cord Q, connecting thepulley with the carriage and. adapted to be wound upon the pulley. Thespring (1 furnishing the power is located inside the pulley and coiledaround its axis q, and its tension is regulated by a worm-gear Q keyedto the pulley-axis and meshing with a worm Q, the axial line whereof ishorizontal. The

worm is furnished with a th umb-nut (1 whereby it may be actuatedreadily and easily, and any adjustment effected by it is automaticallyretained.

The escapement-lever for controlling the feed of the carriage iscomposed of the lever B and the pawl It, mounted and pivoted on thelever. The pawl is made in one piece of metal and alternates with thepoint r of the lever in looking the rack in the usual manner. The pawlis moved into position for fresh engagement with the rackthat is to say,from the position shown at Fig. 10 to that shown at Fig. 12--by a springB. This spring being forced from its normal position in Fig. 12 by powerfrom the carriage, which carries the pawl against the stop 0", is readywhenever the pawl is released to turn it to the position given at Fig.10. A companion spring R3, located at the other side of the pawl fromthat at which spring R is located, is employed simply to retain thecontrol of the pawl and prevent its swinging too far either under thepower of spring R or by its contact with the rack when the carriage ismoved back preparatory to starting a fresh writing-line. The lever B ismounted upon the rock-shaft R, actuated through the arm R the front endof which is lifted at each impression, and also by the spacing-lever R.

I do not claim herein the swinging erasureplate broadly, nor do I claim,broadly, the means whereby it is automatically operated, but reservesuch claims for a copending application, Serial No. 67,914, filed July11, 1901.
